manual update

Hello Everyone,

I'm using calibre since years and I have a question since the beginning.

I always used the distrubution package because I never undestood how to manually update the binaries installation in linux.

I'm a bit tired of the always old distro packages

so could you pls help me to understand how to update after install with this command: sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin install_dir=/opt ?

thanks,
bye,

Alex
